Product Selection Differences for Duplex Metal Seated Butterfly Valves

When selecting Duplex Metal Seated Butterfly Valves, consider the following key differences:

1. Material: Duplex stainless steel offers higher strength and corrosion resistance compared to traditional stainless steel. It is suitable for demanding applications where corrosion, erosion, and high temperatures are concerns.

2. Sealing Mechanism: Metal seated butterfly valves provide tight shut-off with metal-to-metal contact between the seat and disc. Consider the material and design of the sealing surface to ensure a long-lasting and reliable seal.

3. Temperature and Pressure Ratings: Duplex metal seated butterfly valves are designed to operate in high-temperature and high-pressure environments. Ensure that the selected valve meets the specific requirements of your application in terms of temperature and pressure ratings.

4. Flow Characteristics: Consider the flow characteristics of the valve, such as flow coefficient (Cv), pressure drop, and flow regulation capabilities, to ensure optimal performance in your process.

5. Size and End Connections: Select the appropriate size and end connections (flanged, wafer, lug, etc.) based on the piping system requirements and installation considerations.

6. Operation and Actuation: Consider the mode of operation (manual, electric, pneumatic, hydraulic) that best suits your process requirements for control and automation.

7. Certifications and Standards: Ensure that the valve complies with industry standards and certifications relevant to your application, such as API, ANSI, ASTM, and ISO standards.

By carefully evaluating these factors, you can select a Duplex Metal Seated Butterfly Valve that best meets the needs of your specific application.
